INTRODUCTION The HB2800 Flow Monitor is a state-of-the-art, digital signal processing flow monitor, designed to provide the user with exceptional flexibility at a very affordable price. Though designed for use with Hedland flow meters, this display can be used with almost any flow meter producing a low amplitude AC output or contact closure signal(s). This flow monitor is capable of accepting a low-level frequency input for calculating flow rate and total. These calculations can then be displayed in the desired units of measurement. All HB2800 Flow Monitors come pre-calibrated, from the factory, if ordered with a Hedland flow meter. If required, however, it can easily be re-configured in the field. The monitor’s large 8 digit by .75" numeric liquid crystal display makes extended range viewing practical. The second 8 digit by .38" alphanumeric display provides for selectable units viewing in run mode and prompts for variables in programming mode. Finally, the user can choose between displaying rate, total, or alternating between both rate and total.

OPERATING THE MONITOR The monitor has two modes of operation referred to as the RUN mode and the PROGRAM mode. Both the run mode and the program mode display screen enunciators confirming the state of the monitor. A quick glance at the lower left-hand corner of the LCD screen will confirm operating status. Normal operation will be in the RUN mode. To access the programming mode, press the MENU button until the first programming screen is displayed. After programming the display with the necessary information, a lock out feature can be turned on to prevent unauthorized access or changing the meter’s setup parameters. BASIC PROGRAMMING MODE Keys:

MENU – Switches to Programming mode UP Arrow – Scrolls forward through the parameter choices and increments numeric variables RIGHT Arrow – Scrolls backward through the parameter choices and moves the active digit to the right ENTER – Used to save programming information, advance to the next programming parameter, and in the reset process

Modes:

RUN – Normal operating mode PROGRAM – Used to program variables into the display

If your monitor was ordered with a Hedland flow meter, the two components ship from the factory calibrated as a set. If the monitor is a replacement, the turbine’s K-factor has changed, or the monitor is being used with some other pulse generating device, programming will be necessary.

6

Programming Using Pulse Output Turbine Flow Meters Each turbine flow meter is shipped with either a K-factor value or frequency data. If frequency data is provided, the data must be converted to a K-factor before programming the monitor. K-factor information, when supplied, can usually be found on the neck of the flow meter or stamped on the body. The K-factor represents the number of pulses per unit of volume. The K-factor will be needed to program the monitor readout.

ENTER PROGRAMMING MODE – Change to programming mode by pressing the MENU button once. The mode indicator will change from RUN to PROGRAM.

SELECT THE METER SIZE – At the METER prompt, press the UP or RIGHT arrow keys to select the bore size of your meter. Press ENTER button once to save meter size choice and advance to the K-factor units selection.

7

ENTER THE METER’S K-FACTOR UNIT – Directly after the METER size is selected, the display’s K-factor unit must be chosen. Use the UP arrow key to select your K-factor unit. For meters calibrated in gallons, use PUL/GAL (pulses per gallon); for meters calibrated in cubic meters, use PUL/M3 (pulses per cubic meter); etc. Press ENTER to save the K-factor unit and advance to the next parameter.

ENTER THE METER’S K-FACTOR – To change the K-FACTOR value, use the RIGHT arrow key and select the position of the number that you wish to change. Using the UP arrow key, increment the display digit until it matches the meter’s K-factor digit. Repeat this process until all K-factor digits have been entered. Press ENTER once to save the K-factor and advance to the RATE/TOTAL units selection. SELECT THE RATE/TOTAL UNITS OF MEASURE – The monitor allows the choice of five common rate/total units. The monitor shows the rate/total unit that the display is currently set for. If the current selection is correct, press the ENTER key once to advance to the next parameter. To change to an alternate unit, use the arrow keys to scroll to the desired rate unit and press ENTER to save the choice.

NOTE: The meter connection size and the bore size are different. For example, many of the 1" NPT turbines have bore sizes that range from ⅜" up to 1". Be sure to use the correct bore size or the meter will report incorrect flows and totals.

NOTE: Unless otherwise specified, Hedland turbine flow meters are supplied with K-factors measured in pulses per gallon (PUL/GAL) which will automatically convert to your desired units of measure.

NOTE: The K-factor supplied with the meter or calculated from calibration data will be needed to complete next step.

8

SELECT THE DISPLAY FUNCTION – The monitor can display RATE or TOTAL or alternate between BOTH rate and total. If the current selection is correct, press the ENTER key to advance to the next parameter. To change to an alternate display mode, use the arrow keys to scroll to the desired display mode and press ENTER to save the choice. A TEST function is also available in the Display Function sub-menu. With the test function selected, the display acts like a frequency counter and displays the raw input frequency being supplied to the frequency input terminals. This is very useful when troubleshooting flow problems. TOTALIZER PULSE OUTPUT – The pulse output parameter can be either enabled or disabled. When enabled this output generates 20mS duration pulse every time the least significant digit of the totalizer increments. The amplitude of the pulse is dependent on the voltage level of the supply connected to the pulse output and is limited to a maximum 30 VDC. PASSWORD – Password protection prevents unauthorized users from changing programming information. Initially, the password is set to all zeros. To change the password, simply enter any 4 digit code using the arrow keys as previously

NOTE: The total unit’s output multiplier cannot be modified in the Standard program level. This option is reserved for the Advanced program level.

described to enter the password value. Pressing ENTER once will store the password and take you back to the RST PSWD screen.

RST PSWD – The reset password screen allows the operator to enter any 4 digit code for the manual reset totals function.

RESET TOTAL – To reset the monitor total display, in run mode press the MENU and ENTER simultaneously until TOTAL RST starts to flash. The TOTAL RST will stop flashing and the display will return to the run mode at the conclusion of the reset procedure. STORE TOTAL – The current total can be manually stored in the monitor’s flash memory. This procedure may be desirable prior to replacing the battery. Press and hold the ENTER key for 2 seconds. The display will respond with a flashing TOTALSVD and then return to the run mode. AUTOMATIC STORE TOTAL – The monitor is equipped with a store total feature that works automatically, saving the current total to flash memory. The frequency of saves depends on the power supply option chosen.

Battery Powered: Once per hour and just before a low

battery condition turns the unit off. Loop Powered: Once every ten minutes.

NOTE: This password will allow the operator to manually reset totals.

NOTE: This reset password code will not allow the operator to enter the programming mode.

BATTERY REPLACEMENT Battery powered monitors use a single 1.5V, “D” size, alkaline battery. When replacement is necessary, use a clean fresh battery to ensure continued trouble-free operation. It is recommended that the total be saved to memory before the battery is removed. (See STORE TOTAL in the programming section of this manual). Unscrew the two captive screws on the front panel to gain access to the battery. Replace the battery being sure to observe the proper polarity, and then re-fasten the front panel. ADDITIONAL INPUT OPTIONS The HB2800 Flow Monitor is capable of receiving magnetic pick-up input (small signal sine wave) or a contact closure input (pulse). Since most Hedland turbine flow meters utilize a magnetic pick-up, the HB2800 Flow Monitor is shipped configured for magnetic pick-up input. To change to a contact closure input, remove JP2 from the top two pins and jumper them to the bottom two pins. See Figure 2 on page 11.

TROUBLESHOOTING GUIDE

Trouble Remedy

No LCD Display • Check battery voltage. Should be 1.5 VDC. Replace if low or bad.

No Rate or Total Displayed

• Check connection from meter pick-up to display input terminals. • Check turbine meter rotor for debris. Rotor should spin

freely. • Check programming of flow monitor.

Flow Rate Display Interprets Reading Constantly

• This is usually an indication of external noise. Keep all AC wires separate from DC wires.

• Check for large motors close to the meter pick-up. • Check for radio antenna in close proximity. • Try disconnecting the pick-up from the monitor pig tail. This

should stop the noise. If not, then try re-orientating the meter to a new location.

Flow Rate Indicator Bounces

• This usually indicates a weak signal. Replace pick-up and/or check all connections.

• Examine K-factor.

ADDITIONAL SCALING PARAMETERS

HB2800 Standard 4-20 mA Programming Instructions

FLOW 4mA SETTING – When the loop powered option is ordered, the flow rate that corresponds to 4mA must be set. Zero is default flow rate for this setting. If the current selection is correct, press the ENTER key once to advance to the next parameter. If adjustment is required, use the RIGHT arrow key to select the position of the number you wish to change. Then use the UP arrow key to increment the number. Once you have completed this step, press the ENTER key to advance to the next parameter. FLOW 20mA SETTING – The flow rate that corresponds to 20mA must be set next. The turbine meter’s maximum flow rate is the default value. If the current selection is correct, press the ENTER key once to advance to the next parameter. If adjustment is required, use the RIGHT arrow key to select the position of the number you wish to change. Then use the UP arrow key to increment the number. Once you have completed this step, press the ENTER key to advance to the next parameter. 4-20mA CALIBRATION – When ordered with a 4-20mA option, this menu item allows the fine adjustment of the 4-20mA output. The 4mA setting is typically between 35 and 50. To set the 4mA value, connect an ammeter in series with the loop power supply. At the 4mA OUT prompt, adjust the 4mA value to obtain a 4mA reading on the ammeter. The UP arrow key increments the value and the RIGHT arrow key decrements the value. When a steady 4mA reading is obtained

NOTE: The programming instructions below are only available when purchasing a loop powered unit. Battery powered units will not see these programming choices.

on the ammeter, press the ENTER key to lock in this value and move to the 20mA adjustment. The 20mA adjustment is performed using the same procedure as the 4mA adjustment. 4-20mA TEST – The monitor contains a diagnostic routine that allows the simulation of mA values between 4 and 20 to check output tracking. At the 4-20TEST prompt the arrow keys change the simulated mA output in increments of 1mA. The ammeter should track the simulated mA output. If a 4-20mA test in not necessary, pressing the ENTER key once will escape the testing at any time.

NOTE: If your HB2800 Flow Monitor was ordered with a a Hedland turbine flow meter, the 4-20mA was programmed and factory calibrated.
